7 Operation Figure 1 Block Diagram -48V Fed Converter Shelf -48V power input is distributed in an A and B redundant fashion to each of the converter cards and the alarm card. There are two +/-190V circuits on each converter card. The circuits both boost the voltage and limit the current as prescribed by UL and GR-1089-CORE. Warning: Ground faults or short circuits on the output do not permanently disconnect the output. The converter circuit tests the line every 4 seconds and will re-energize if the wiring fault is cleared. A serial communication bus links each converter to an alarm card at the end of each shelf. The alarm card provides major and minor form C contacts, manages the converters and relays information to an optional system controller using Galaxy Protocol over an RS485 bus. Up to 24 shelves can be controlled and monitored by one system controller. The controller is WEB and SNMP capable r04 December

16 Inspect the Network Check and Mark Wiring Compliance The system is classified as an A2 circuit tested according to GR-1089-CORE Issue 3. As such, each location in the network where the output is available to be touched must be protected and marked as an A2 voltage. Step Action 1. Is accessibility to the circuit throughout the network consistent with A2 requirements? 2. Is the 5-pin protector marked as a special circuit? 3. Does the 5-pin protector protect each pair to a level corresponding to a CommScope 3C*EW Gas tube primary protector? This protector has a voltage breakdown range of Volts and an impulse spark over range of < Volts. Protectors with a lower voltage breakdown rating will be problematic. Verify UL Installation Compliance This verification is required at the time of installation to meet UL Perform this verification before power is distributed in the network. Normally the final step is performed by closing the circuit using a 5-pin protector after DC power is applied to the system. Step Action 1. Recognize that the Remote Feed Telecommunication Voltage limited (RFT-V) circuit is voltage limited to +190V and -190V from ground. 2. Is the total capacitance to ground on each line of the circuit less than 10μF? The QS982 introduces 4.4μF. The remote electronics and line must introduce less than 5.6 μf of capacitance.. 3. Is the total capacitance line to line of the circuit less than 40μF? The QS982 introduces 2.2μF. The remote electronics and line must introduce less than 37.2 μf of capacitance from tip to ring. 4. Is the remote equipment also a RFT-V voltage limited circuit? Both ends of the circuit must be designed to the same standard. This must be verified before the equipment is connected together. 5. Is the voltage rating of the Network Wiring sufficient to support 190V to ground? 6. Is the wire between the converters and primary protectors minimum 26AWG 200V rated? 7. Is the chassis of the system bonded to ground? Verify by both observation and measurement before powering the system. Measurement from the exterior of the Converter Shelf to the cabinet ground bus should indicate continuity as determined via a meter providing an audible beep or the standard method of continuity verification used in the network. Many network providers use a maximum value of 10 ohms r04 December

17 8. Test each circuit by powering an open circuit at the remote end of the wire with a QS982 output. If red lights do not flash, there is no leakage path to ground at operating voltage. If the FLT light does not blink yellow, there is no hard short between tip and ring. Note: 1. This step is shown here only for completeness. It is to be performed after the Apply DC Power section is completed. 2. Circuit powering is usually accomplished by closing the circuit using a 5-pin protector after DC power applied to the system.

Vertical Spacing, Airflow, Baffles, and Fan Shelves Overview The Converter System has been designed for mounting in relay racks or in equipment cabinets. It is designed for use with user provided vertical airflow cooling of at least 175 linear feet per minute over the entire flow cross-section of the shelf. Equipment may be placed on top of the provided airflow is not impeded or sufficient spacing is provided. Outdoor Cabinet Application The Converter System is rated to work to 65 C in stacks of two shelves in outdoor cabinets without baffles. Note: where the air entering the second shelf may be heated above 65C inlet temperature, additional airflow beyond the minimum 175 linear feet per minute is required. These cases require an engineered solution. Central Office Application Converter Shelf Stacks (Figure 2) are rated to operate in 55 C environments. Up to 2 Converter Shelf Stacks may be mounted in a single frame. No vertical space between: Fan Shelves Fan Shelf and Converter Shelf Converter Shelves A 3 inch minimum horizontal space is required to the rear of the baffle. Specific testing is required If the space available is less than 3 inches. Slot covers must be installed used on all empty Converter slots when more than one Converter shelf is being cooled by a Fan Shelf. These covers prevent cooling air from bypassing the Converters. See Figure 29. Figure 29 Converter Slot Covers r04 December

40 Precautions Install, service, and operate equipment only by professional, skilled and qualified personnel who have the necessary knowledge and practical experience with electrical equipment and who understand the hazards that can arise when working on this type of equipment. Disconnect batteries from outputs and/or follow safety procedures while working on equipment. Batteries may be connected in parallel with the output of the rectifiers. Turning off the rectifiers will not necessarily remove power from the bus. Do not disconnect permanent bonding connections unless all power inputs are disconnected. Verify that equipment is properly safety earth grounded before connecting power. High leakage currents may be possible. Exercise care and follow all safety warnings and practices when servicing this equipment. Hazardous energy and voltages are present in the unit and on the interface cables that can shock or cause serious injury. When equipped with ringer modules, hazardous voltages will be present on the ringer output connectors. Use the following precautions in addition to proper job training and safety procedures: Use only properly insulated tools. Remove all metallic objects (key chains, glasses, rings, watches, or other jewelry). Follow Lock Out Tag Out (LOTO) procedures: customer specified, site specific, or general as appropriate. Disconnect all power input before servicing the equipment. Check for multiple power inputs. Wear safety glasses. Follow Personal Protective Equipment requirements: customer specified, site specific, or general as appropriate. Test circuits before touching. Be aware of potential hazards before servicing equipment. Identify exposed hazardous electrical potentials on connectors, wiring, etc. Avoid contacting circuits when removing or replacing covers. Use a personal ESD strap when accessing or removing electronic components. Follow procedures for working at heights more than 4ft above the floor: customer specified, site specific, or general as appropriate.

41 Appendix A: Operating Temperature Measurement and Vertical Spacing Overview The has been designed for mounting in relay racks or in equipment cabinets. It is designed for use with user provided vertical airflow cooling of at least 175 linear feet per minute over the entire flow cross-section of the shelf. Equipment may be placed on top of the provided airflow is not impeded or sufficient spacing is provided. A 1U Baffle is required above the highest converter shelf; this baffle provides sufficient vertical spacing. Direct the airflow into a 3 inch minimum space. If the spacing is less than 3 inch spacing application specific testing is required. Operating Temperature The is rated to work to 65 C in stacks of two shelves in outdoor cabinets without baffles. Note: in outdoor cabinets where the air entering the second shelf may be heated above 65 C inlet temperature, additional airflow beyond the 175 linear feet per minute is required. These cases require an engineered solution. In Central Office environments when baffles are required for safety reasons, a three shelf system is rated to operate in 55 C environments. Baffles and Fan Trays For Central Office applications, baffles are used between every set of three Converter shelves. Fan Shelves are required for every set of three Converter shelves. No more than 6 shelves may be located in a particular frame. Slot covers must be used on all empty slots when more than one shelf is being cooled by a particular airflow device. Always mount converter shelves above the fan tray that cools them. Leave no space between the top of a fan tray and the converter shelf above it. The Fan Shelf draws air down through whatever equipment is located directly above it. If a gap is left above a fan tray, air will be drawn into the fan tray from the aisles rather than from the converter shelf above the fan tray. This will result in service effecting problems due to insufficient cooling air flowing through the active converters. The Fan Shelf forces air up through whatever equipment is located directly above it. If a gap is left above a fan tray, air will escape into the aisles rather than flowing into the converter shelf above the fan tray. This will result in service effecting problems due to insufficient cooling air flowing through the active converters. Always mount a converter shelf immediately above a fan shelf or above a converter shelf stacked on a fan shelf. Any gaps between converter shelves, or absence of slot covers, can cause service effecting problems. Note: All unpopulated converter slots must be filled with slot fillers. For example the figure below shows a shelf with operational converters in the first two slots and slot fillers in the remaining 10 slots: Figure 33 Converter Slot Fillers r04 December

44 Appendix C: Operation without a Controller - Alarm Wiring Each converter shelf provides alarm contact closures for Power Major and Power Minor independently of a controller. Wire these relays into the alarm network in deployments where a controller is not utilized. When a controller is installed then an alarm cable can be attached to the controller see the Connect Office Alarms section. Step Action 1. Attach the required alarm leads to the office alarm screw terminals (TB1 on the alarm card) as designated. 2. Reinstall Alarm card and close distribution door. Figure 34 Office Alarm Pin Outs - Alarm Cards Converter Shelf Alarm Card State Table This section shows Alarm and LED response for the Alarm Card LEDs and Relays: The Converter Shelf contains a pair of A bus feeds and a pair of B bus feeds. The use of dual A and B feeds is to not exceed the 48 AMPS L2 input current per feed. The A bus feeds are designated A1-6 and A9-12, and power shelf slots 1-6 (left side) and 7-12 (right side) respectively. The B bus feeds are also designated in an identical fashion. The alarm card monitors the -48v on each of these four feeds, and asserts alarms and indicators - Table 11.

45 Alarm Card Logical Operation of LEDs and Alarm Relays The Alarm Card contains a pair of form C relays to provide shelf PMN and PMJ isolated closures. Both PMN and PMJ relays will signal alarm if both A and B input fail. Relays coils are energized to signal normal (no-alarm) and are redundantly powered by both the A & B input buses. The relay circuit interfaces to a pair of parallel buses connected to each of the 16 Converter/Limiter Cards. Each Converter has an open collector output on the bus, and pulls the bus low to chassis ground when it is asserting an alarm. The PMN/PMJ circuit on the Alarm card recognizes the bus state change and denergizes the associated alarm relay, signaling alarm. The alarm card separately monitors both the PNM and PMJ bus. When the PMN bus is active (pulled low), the Alarm card asserts a PMN relay and lights the ALM LED Yellow. When the PMJ bus is active (pulled low), the Alarm card asserts a PMJ relay and lights the ALM LED Red. The Alarm Card ignores the state of the PMN bus (and does not assert a PNM relay/led action) while an active PMJ is present. This is necessary since a single LED is used for both Minor (Yellow) and Major (Red) visual indication. The Alarm Card also monitors the -48V dc inputs and asserts PNM/PMJ for conditions as described in the earlier section dealing with input voltage monitoring. The Alarm Card also monitors the two fan tray alarms. When either of the two fan tray alarms is active, the Alarm Card asserts a PMN relay and Yellow ALM LED. When both of the fan tray alarms are active, the Alarm Card shall assert a PMJ relay and Red ALM LED. The Alarm Card shall also monitor its internal I 2 C to RS-485 conversion processor. A failure of this processor shall constitute a PMN condition r04 December

46 Alarm Card Office Alarms Each Shelf provides alarm contact closures for Power Major and Power Minor. Wire these relays into the alarm network if desired. Systems equipped with a controller provide all alarms via the controller alarm connector and require no office alarm wiring to alarm cards. Inter-Shelf Signal Cables are only required between Fan Shelves and the adjacent Converter Shelf in systems without a Controller. Step Action 1. Install Alarm Card Cables Attach the office alarm leads to the office alarm screw terminals of alarm card TB1 per site engineering instructions.
